Cucumber mosaic is a viral disease of worldwide distribution that affects over 1200 plant species. Hosts include a wide range of fruits, vegetables, herbaceous and woody ornamentals, and weeds.
Who spread the cucumber mosaic virus?
Spread: This virus is spread by several aphid vectors. Aphids aquire and transmit virus particles by probing and/or feeding on plant tissues. An aphid can transmit the virus to susceptible plants for up to two hours after acquiring the virus from an infected plant.
Which of the following crop is reservoir host of cucumber mosaic virus *?
It has a host range of more than 1,200 species, and is transmitted by many species of aphids, as well as cucumber beetles. Vegetable hosts include carrot, celery, cucurbits, legumes, lettuce, onion, pepper, spinach, tomato, and rarely potato. Many woody and non-woody ornamentals are also hosts.
Which plants are affected by cucumber mosaic virus?
As can be inferred from its name, cucumber mosaic virus often affects cucumbers, but it is also a common problem for many other garden plants, including other cucurbits (melons, squashes), nightshades (tomatoes, peppers, eggplants, potatoes), and leafy greens (lettuce, spinach).
How do cucumbers control the mosaic virus?
- Purchase virus-free plants.
- Maintain strict aphid control.
- Remove all weeds since these may harbor both CMV and aphids.
- Immediately set aside plants with the above symptoms and obtain a diagnosis.
- Discard virus infected plants.
- Disinfest tools used for vegetative propagation frequently.
Can you eat cucumbers with mosaic virus?
Yes, you can eat squash and melons that are infected with mosaic virus. These viruses are not harmful to humans and do not cause the fruit to rot. Often the discoloration is only skin deep. In cases where fruit are severely distorted, the texture of the fruit may be affected and may not be desirable for eating.
What does mosaic virus look like on cucumbers?
A green- to dark-green mosaic with vein banding occurs on cucumber leaves, and leaves may show narrow, elongated growth if infected when young. The fruit of WMV infected plants are typically stunted, gnarled, and sometimes knobby.
Where does cucumber mosaic virus come from?
Where does cucumber mosaic come from? Cucumber mosaic is caused by Cucumber mosaic virus (CMV) which can overwinter in susceptible biennial or perennial weeds, as well as in perennial agricultural crops (e.g., alfalfa) and perennial herbaceous and woody ornamentals.
What is Dasheen mosaic virus?
Dasheen mosaic virus (DsMV) is one of the important viral pathogen of C. esculenta, which develops pale green feathering symptoms, or may have severe or slight vein-banding symptoms or no visible symptoms at all. The virus causes variation patterns in colour, shapes, and sizes of the leaf and may reduce the corm yield.
Can tomatoes get cucumber mosaic virus?
Tomatoes infected with the cucumber mosaic virus develop a slight yellowing and mottling of the older leaves. Expanding leaves typically become twisted, curl downward, and develop a “shoestring” appearance as a result of a restriction of the leaf surface to a narrow band around the midrib of the leaf.
Can you treat cucumber mosaic virus?
Cucumber Mosaic Virus Treatment
Prevention is difficult because of the short time between when the aphid contracts the virus and its passing it along. Early season aphid control may help, but there is no known Cucumber Mosaic Virus treatment at the present time.
Can mosaic virus live in soil?
Tomato mosaic virus and tobacco mosaic virus can exist for two years in dry soil or leaf debris, but will only persist one month if soil is moist. The viruses can also survive in infected root debris in the soil for up to two years.
Can cucumber mosaic virus spread to other plants?
Cucumber mosaic virus can infect plants from over forty families, including vegetable crops like tomato, lettuce and spinach, flower crops like gladiolus, petunias, impatiens and rudbekia, and a wide variety of weeds. All of the mosaic viruses can also infect weeds in the cucurbit family.
